General Discussion

No one, that I know of, is claiming that the data is fraudulent.

The point is that Manning stole the information en masse and then passed it along for distro.

A true "whistleblower" passes out information that shows that the organization they belong to is conducting some sort of specific illegal act.

Secret diplomatic cables are necessary to conduct the business of diplomacy. The same goes for mission SITREPs, orders and the like.

If you want to make the case that the helicopter footage was evidence of a "war crime" (which it wasn't), then he should take the consequences of his actions. Mass dumps of data like this are just attempt to hurt and embarrass the United States and make diplomacy harder.
